    "abstract": "Interference effects in quantum transitions, giving rise to amplification\nwithout inversion, optical transparency and to enhancements in nonlinear\noptical frequency conversions are considered. Review of the relevant early\ntheoretical and experimental results is given. The role of relaxation\nprocesses, spontaneous cascade of polarizations, local field effects,\nDoppler-broadening, as well as specific features of the interference in the\nspectral continuum are discussed.",
